Fans in for treat as producers move to exploit opportunity

World of Warcraft fan Yan Feng has had a replica of Frost-mourne, one of the online game's most powerful weapons, in his Beijing apartment for years.

But, despite having spent 1,000 yuan ($154) then to buy the sword on e-commerce site Taobao, all Yan got was pirated copy.

Explaining why he opted to buy the fake, Yan, who's been fascinated by the game for more than a decade, says: "There were only 1,000 official pieces made globally and they sold out very quickly. Also, it was not easy to buy one in the Chinese mainland then."
